breezy

What file can I edit, or gconf key, so that when I insert a USB memory stick drive, it loads Thunar instead of Nautilus? I use Thunar now instead of Nautilus because it's zippier. (BTW, I even use it on my fast machine at the office too.)

I have Ubuntu Breezy.

My screensaver on my Office Ubuntu Breezy is locking up occasionally. The one at home is not. Both are set on blank screen.

Unless you can help me figure out what's locking up screensaver, I'd like to permanently disable it and just do ALT+F3 when I leave at night. (No one in my office knows Linux well enough to get in. Plus, we have tight security.)

Need some help if you could please. Using Breezy 5.10, my iptables firewall script doesn't let me pass NTP stuff except by command-line /usr/sbin/ntpdate. I know that all NTP needs is 123 UDP, but for some reason the gnome date/time applet in the GUI won't let me click "Synchronize" unless I drop my firewall. Can you identify for me what might be the cause? Here's my current /etc/firewall.sh script:
